Abstract
The disclosure provides a method for evaluation of removal of nitrogen-containing organic matter from the wastewater. The method includes: 1) pretreating a wastewater sample from a wastewater treatment plant; enriching nitrogen-containing organic matter in the wastewater sample with a solid-phase extraction cartridge; separating the nitrogen-containing organic matter from a substrate and disruptors of the wastewater sample, and collecting the nitrogen-containing organic matter; 2) detecting and analyzing the nitrogen-containing organic matter collected in 1) with a Fourier-transform ion cyclotron resonance mass spectrometer, thereby obtaining mass spectra of the nitrogen-containing organic matter; 3) preprocessing peak data of the mass spectra of the nitrogen-containing organic matter in each wastewater sample; setting the nitrogen-containing organic matter corresponding to the peak data as a global variable; arranging wastewater samples into cross-sectional data according to wastewater treatment processes; creating an assessment matrix for evaluating removal of the nitrogen-containing organic matter.
